You’re at a parent-teacher conference on the eve of the first day of a new school year. Your daughter is going into freshmen algebra tomorrow and you’re at this conference to meet her new teacher. You show up armed with every math quiz, every math problem that your child has attempted throughout elementary and middle school, as well as a breakdown of how long she took on each and at what time during the day—after breakfast, before dinner—she performed best. The profile may even reveal whom your daughter talks to online, whom she studies with, and how those supposed friends influence her homework performance. This is a lot of information to carry around. If you were to print all this material, you would be dragging boxes along behind you. But this information is already stored on the cloud. All you have to do is give your child’s teacher a link. You have a request: “Would you mind taking all this data and creating an individual learning program for my daughter to make positively sure she finishes this year with an understanding of algebra?
